as many said its not worth merching right now s market is unstable and price of weapons and gears are only gonna fall in future. what i would suggest to invest in is ankh kits and cryo locks coz its sure that new gears would come in cryo locks plus ankh kits would be in demand when new elites hit up but you cant be 100% sure of what and how sts would bring a new content and how it would effect the market. it may be possible that no new loot come with new elites in that case luck kits and ankh kits would not be that good, so my advice is to currently farm locks or arena only and wait for some updates
